IMPROVEMENT IN GAS-BURNER SOCKETS.

Specification forming part of Letters Patent No. 42,609, dated May 3,1864'; antedatcd April 1, 1864.

To all whom it may concern.-

Be it known that I, JOSEPH TODD, of Madison, in the county of Jefi'ersonand State of Indiana, have invented a new and useful Improvement inGas-Burner Sockets; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing, forming part of this specification, saiddrawing representing a central vertical section of a socket.

This invention relates to the sockets by which portable pendants or theflexible tubing of the portable table-stand lights are attached to theburners of gasoliers or gasbrackets. These sockets are made of twopieces, between which the india-rubber or other elastic packing ring orrings are commonly secured by barring the edge of one piece over ashoulder provided on the other but this mode of securing the packingdoes not provide for the adjustment, renewal, or contraction of thepacking, which, by the frequent removal of the socket from the burnerand its replacement thereon, soon wears so as to fit the burner tooloosely to prevent the escape of gas around it.

The object of my invention is to provide Y for the renewal, adjustment,and contraction of the packing to make it fit the burner tightly; and tothis end it consists in uniting the two parts of the socket by means ofa male screw-thread on one and a correspondin g female screw in theother, by which means the packing is enabled to be compressed in thedirection of the length of the burner, thereby causing the contractionof its opening and make it fit tightly to the burner.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is the lower, and B the upper, piece of the socket, the lower piecemade of suitable form to fit over the burner, and the upper piece ofsuitable form to receive the end of the pendent pipe or the hooked pipewhich attaches the flexible tube of the table-stand light. The upperpiece has the lower part of its interior enlarged to form a shoulder, a,and below this shoulder ,there is out within it the female screw-threadc. The upper part of the exterior of the lower piece has cut upon itsexterior the male screw-thread b,which fits the female screw-thread 0. eis theindia-rubber or other elasticpacking, com posed of one or morerings. The exterior circumference of this packing is such that it willenter easily 'into the lower part of the upper piece, B, and restagainst the shoulder a, and its interior circumference is such that inits normal condition it will fit easily to the burner. The lower piece,A, being screwed into the upper piece, B, confines the packing againstthe shoulder a, and by screwing it in a little farther it is made tocompress the packing in the direction of the length of the socket, andso contract its central opening and adjust it tightly to the burner, andin this way any wear iscompensated for and a tightjoint always obtained.

The male thread might be made upon the lower part of the upper piece, B,and the female thread in the interior of the lower piece, A, by makingthe two pieces respectively of proper form.

What I claim as my invention, and desire to secure by Letters Patent,is-

Uniting the two pieces of the gassocketby means of a male and femalescrew-thread, by which the elastic interior packing is renderedadjustable, substantially as herein described.
